We look at the division of 23961251 by 408 
Let's see how many times 408 fits into 23961251.

Let's proceed to step 1:
408 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 408

Step 2:
When dividing 23 by 408, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 408

Step 3:
The number 408 fits into 239 0 times, leaving a remainder of 239.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 239, we get 239.
Include the next digit (6) from the dividend after 239, then repeat: 2396 / 408

Step 4:
2396 divided by 408 is 5 with a remainder of 356.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 356 after subtracting 2040 from 2396.
Fetch the next digit (1) from the dividend, attach it to 356 and continue: 3561 / 408

Advancing to step 5:
If we divide 3561 by 408, we get 8 and a remainder of 297.
The next digit of our result is 8. 
Result so far: 58.0
Subtract 3264 from 3561 to get 297.
Fetch the next digit (2) from the dividend, attach it to 297 and continue: 2972 / 408

Moving on to step 6:
408 goes into 2972 7 times with a remainder of 116.
Write down 7 as next digit of the result. 
Result so far: 587.0
Deduct 2856 from 2972 and we're left with 116.
Grab the next digit (5) from the dividend, add it to 116, then carry on: 1165 / 408

Let's proceed to step 7:
When dividing 1165 by 408, we get 2 with a remainder of 349.
Put 2 as the next digit of the answer. 
Result so far: 5872.0
If we take 816 away from 1165, we end up with 349.
Fetch the next digit (1) from the dividend, attach it to 349 and continue: 3491 / 408

Advancing to step 8:
3491 divided by 408 is 8 with a remainder of 227.
The number 8 becomes the next digit in our result. 
Result so far: 58728.0
Subtracting 3264 from 3491 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Let's proceed to step 9:
408 goes into 2270 5 times with a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 58728.5
The remainder is 230 after subtracting 2040 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
408 goes into 2300 5 times with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 58728.55
Deduct 2040 from 2300 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 58728.55 and a remainder of 0.26.
